+A STATEMENT ON LEGACY SUPPORT
+
+In the terminal world there is much cruft that comes from old and unsup‐
+ported terminals that inherit incompatible modes  and  escape  sequences
+which noone is able to know, except when he/she comes from that time and
+developed a graphical vt100 emulator at that time.
+
+One  goal  of  st is to only support what is really needed. When you en‐
+counter a sequence which you really need, implement it.  But  while  you
+are  at it,  do not add the other cruft you might encounter while sneek‐
+ing at other terminal emulators. History has bloated them and  there  is
+no real evidence that most of the sequences are used today.

+st - simple terminal
+
+
+How to install:
+
+- Extract the downloaded zip file
+- Copy the files to "Roms/APPS/" folder
+
+How to run:
+
+- From your device main menu -> RA Game -> APPS -> SimpleTerminal (or SimpleTerminal-HighRes)
+
+
+
+--------------------
+st is a simple virtual terminal emulator for X which sucks less.
+
+Modified to run on RS-97.
+=> line doubling to deal with the 320x480 resolution
+=> TTF fonts replaced by embedded pixel font (from TIC-80)
+=> onscreen keyboard (see keyboard.c for button bindings)
+
+Keys: 
+- pad: select key
+- A: press key
+- B: toggles key (useful for shift/ctrl...)
+- L: is shift
+- R: is backspace
+- Y: change keyboard location (top/bottom)
+- X: show / hide keyboard
+- SELECT: quit
+
+
+Requirements
+------------
+In order to build st you need the Xlib header files.
+
+Build
+------------
+For generic linux:
+    make
+
+For RG35XX Plus:
+    ./build-rg35xxplus.sh
+    (or run inside rg35xxplus-toolchain docker container: UNION_PLATFORM=rg35xxplus make)
+
+For generic linux (with bigger window size)
+    UNION_PLATFORM=upscale make
+
+
+Running st
+----------
+
+    ./build/SimpleTerminal
+
+Run with High resolution
+    HIGH_RES=1 ./build/SimpleTerminal
+
+
+If you don't install st, define TNAME to "xterm" in config.h or make sure to at
+least compile st terminfo entry with the following command:
+
+    tic -s st.info
+
+It should print the path of the compiled terminfo entry. You can
+safely remove it if you don't plan to use st anymore.
+See the man page for additional details.
